I personally would no longer bother with a P3 driver; Alex's drivers from LaserTack are better:

Also... While Norty is right, you don't necessarily want to set your bias current to a hair under threshold, (such that you get laser output at "1%" brightness in software.
Most drivers won't hit lasing until around the rather meaningless 10% on the software power level.
I would look at what level your red and blue stop lasing on the software power slider, and adjust your new green to come on at the same point.
It's not wrong to do either, both can be corrected by setting colour pallets, but should you plug the projector into a controller that doesn't have your colour pallet set, colour rendition will be better by having the thresholds all at the same point.
